Abstract

Summary

Nine hundred and one wild-animal serum specimens (amphibian, reptilian, avian, and mammalian) from St. Lawrence County, New York, were examined by hemagglutination-inhibition and neutralization techniques for evidence of Eastern and Western encephalomyelitis, Powassan, St. Louis encephalitis, Maguari, and Cache Valley arbovirus reactivity.

Group A antibody was infrequent. One Chrysemys p. picta serum had detectable EE neutralizing antibody, and a 1:20 serum dilution inhibited hemagglutination of EE antigen. Five mammalian serum specimens (one Lepus americanus, two Marmota monax, and two Vulpes fulva) demonstrated WE neutralizing antibody.
